PIIXIDE(4)

📦 version 11.0, in nixpkgs unstable

💅 PIIXIDE(4) — like, the Intel IDE/SATA disk controllers driver bestie 💖

okay so real talk, this one's from the Kernel Interfaces Manual and it's honestly such a mood. sit down, grab a strawberry 🍓, and let me tell you about piixide.

✨ NAME ✨

piixide — the Intel IDE/SATA disk controllers driver. that's it, that's the vibe. no cap.

🦋 SYNOPSIS 🦋

piixide* at pci? dev ? function ? flags 0x0000

look at her. iconic syntax. she's giving main character energy on the PCI bus 💅

🌸 DESCRIPTION 🌸

so the piixide driver is literally the plug for all the Intel PIIX, PIIX3, PIIX4, and 82801 controllers — and when I say 82801 I mean the whole squad: ICH/ICH0/ICH2/ICH3/ICH4/ICH5/ICH6/ICH7/ICH8/ICH9/ICH10 IDE/SATA controllers. yes, all of them. we don't leave anyone out of the group chat 👑

and what does she actually do? she provides the interface with the hardware for the ata(4) driver. that's the whole job, and she does it flawlessly, periodt ✨

now bestie, listen, there's this one flag and it's kind of a big deal:

  • the 0x0002 flag forces the piixide driver to disable DMA on chipsets where DMA would normally be enabled.

so like… why would you ever do that? two reasons, iykyk:

  • it's a debugging aid — very "let me just turn this off and see what happens" energy 🙈
  • or it's a workaround for those situations where the IDE controller is wired up to the system incorrectly. yeah. the hardware said "not me being chaotic" 💀
fr fr, don't just set this flag for funsies — it's a DMA-off switch, so know why you're flipping it 🫶

🎀 SEE ALSO 🎀

go read her friends, they're all icons too:

💀 BUGS 💀

okay so this is the part where we keep it real 😭

the timings used for the PIO and DMA modes for the controllers listed above? they're for a PCI bus running at 30 or 33 MHz. so if you're out here overclocking your system, this driver may not work properly. that's not a vibe, that's a warning, bestie 🚩
